how to remove a base from a tv

The base has two to four screws that go through the base and into the main TV body (usually two on the back when the TV is on the stand and two up through the bottom of the stand). The stand actually "clicks" or "locks" in when you install it, so it will take some effort to remove it once all of the screws have been removed. I have not been able to find a ‘release’ button to remove it without all of the force after removing the screws.
